Synchrony based evolution of microtubule and its applications
Abstract
Exploring protein with only one resonating circuit had restricted its application within the domain of chemical self-assembly. We find that the secondary structures of proteins build multiple resonating circuits, for tubulin, seven circuits resonantly vibrate to synchronize ~40000 tubulins instantly even under non-coherent pumping. Radio-wave induced synchrony is so robust that it turns tubulin’s condensation reaction 200000 times faster by arranging them in cylindrical shape even before the reaction begins. The momentary burst of laser-like signal during condensation depicts a phase and frequency locked synchrony that enables microtubule to exhibit identical electronic properties for any length. When molecules that evolve different species are pumped with tubulin, condensation fuses them to those seven regions; new properties are added, keeping fundamental properties intact. This shades light on the programming of nature’s complex evolution, provides tool to atomically engineer synchrony for rapid production of new generation materials and instantly test newly designed drugs.

Looking for neutral modes in non-abelian quantum hall states via thermoelectric effect
Abstract
Recent experimental developments in detection and manipulationof quantum hall states with quasi-particles excitations followingnon-abelian statistics have raised hopes for building topologicalprotected quantum bits which form fundamental units of a topologicalquantum computer. I will first discuss recent experimental attempts todetect the non-abelain nature of the u = 5/2 quantum hallstate. Then I will talk about our theoretical proposal for detection ofneutral modes which exist at the boundary of the u = 5/2 quantum hallstate which is believed to be a direct reflections of the existenceof non-abelain quasi particle in the bulk. For detecting a neutral mode itis natural to look for thermal response rather then electrical response.But measuring thermal response in a controlled way is a formidable task inreal life experiments. I will discuss a setup, which can get around thisproblem by using a quantum point contacts in series follows by a shotnoisemeasurement. I will also discuss some very recent theoretical andexperimental developments which involve the use of a quantumdot as a thermoelectric probe for neutral modes.

Precision nuclear physics measurements : Their Context and importance
Abstract
In this talk I will present some recent results from precision nuclear physics experiments using both stable and radioactive ion beam facilities. A part of this talk will focus on isospin symmetry breaking in A = 32 nuclei and its relationship to fundamental tests of the Standard Model.
